springboot2.0 打jar沒有主清單 異常

 springboot打jar包先加入依賴

<plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-compiler-plugin</artifactId>
          <configuration>
            <source>1.8</source>
            <target>1.8</target>
          </configuration>
        </plugin>
        <plugin>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-maven-plugin</artifactId>
          <configuration>
            <mainClass>com.Start</mainClass>
          </configuration>
          <executions>
            <execution>
              <goals>
                <goal>repackage</goal>
              </goals>
            </execution>
          </executions>
        </plugin>

jar包運行報沒有主清單異常緣由

    1.沒有指定啓動類pom文件中指定啓動類

        

        

    2. <pluginManagement>標籤緣由註釋掉便可
